Broken Hill Gravity (P199427), gravity point data

Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose. This Broken Hill Gravity (P199427) contains a total of 3417 point data values acquired at a spacing between 30 and 120 metres. The data is located in NSW and were acquired in 1994, under project No. 199427 for CRA Exploration Pty Ltd.

重力数据（Gravity data）用于测量由地球表面以下岩石密度变化引起的重力微小变化。采集的数据通过标准方法处理，以确保记录的响应仅源于地下岩石。处理结果生成的数据集经解释可揭示地下地质结构。GA的地球物理学家会对处理后数据进行质量核查，确保GA发布的最终数据符合用途（fit-for-purpose）。
